Native to Western USA and similar to alliums, ookow, Dichelostemma congestum, bears tight, long-lasting heads of pretty purple flowers on wiry stems. Like alliums it thrives in full sun and well-drained soil, but has grassy foliage, which starts to die down as the flowers form.
Grow Dichelostemma congestum in a sheltered, sunny spot in well-drained soil. Be careful when cutting the flowers as the sap can irritate the skin. Not fully hardy, bulbs may need a protective mulch laid over them in winter in colder regions, or simply dig up and overwinter in a pot in a cool greenhouse.
